When developing Laravel projects, it is a common requirement to provide timely and beautiful feedback to users. Recently, when I was working on a project, I encountered a problem: I needed to display concise and clear notification information after the user operated, but I didn't want to spend a lot of time customizing a complex notification system. After some exploration, I discovered the Composer package laracasts/flash, which not only solved my problem, but also greatly improved the user experience.
Installation and configuration
Using laracasts/flash is very simple, just install it through Composer:
<code class="language-bash">composer require laracasts/flash</code>
After installation, the default CSS class is optimized for Twitter Bootstrap, so you need to introduce Bootstrap's CSS in your HTML or layout file:
<code class="language-html"><link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"></code>
How to use
In the controller, just call the flash() function before performing the redirect:
<code class="language-php">public function store() { flash('Welcome Aboard!'); return home(); }</code>
You can also set different notification types as needed:
-
flash('Message')->success(): Set the notification topic to "Success". -
flash('Message')->error(): Set the notification topic to "Error". -
flash('Message')->warning(): Set the notification topic to "Warning". -
flash('Message')->overlay(): Display notifications in overlay form. -
flash()->overlay('Modal Message', 'Modal Title'): Shows the modal overlay with the title. -
flash('Message')->important(): Add a close button for notification. -
flash('Message')->error()->important(): Shows the "Error" notification that needs to be closed manually.
In the view, you can use preset templates to display these notifications:
<code class="language-php">@include('flash::message')</code>
Example
Here is a simple HTML example showing how to use laracasts/flash in a page:
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
</head>
<body>
<div class="container">
@include('flash::message')
<p>Welcome to my website...</p>
</div>
<!-- 如果使用 flash()->important() 或 flash()->overlay()，需要引入 Twitter Bootstrap 的 JS -->
<script src="//code.jquery.com/jquery.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<script>
$('#flash-overlay-modal').modal();
</script>
</body>
</html>If you need to modify the notification template, you can run the following command:
<code class="language-bash">php artisan vendor:publish --provider="Laracasts\Flash\FlashServiceProvider"</code>
In this way, the package's view file will be copied to resources/views/vendor/flash/ directory, and you can modify it as needed.
Advanced features
Hide notifications
If you want the notification to be automatically hidden after a few seconds of display, you can use the following JavaScript code:
<script>
$('div.alert').not('.alert-important').delay(3000).fadeOut(350);
</script>
This will cause non-important notifications to fade out after three seconds of display.
Multiple notifications
If you need to display multiple notifications in one operation, just call flash() function multiple times:
<code class="language-php">flash('Message 1'); flash('Message 2')->important(); return redirect('somewhere');</code>
This way, the user will see two notifications after redirecting.
Summarize
laracasts/flash is a simple and powerful tool that makes it extremely simple and efficient to implement flash notifications in Laravel projects. Through this package, I not only solved the notification issues in the project, but also improved the user experience, making the entire application more friendly and professional.
